Yes they will it will have the same characteristics but If it was in the ground and you up root her you might have sum problems, I have never uprooted a plant that was inn the ground and I would think it would react poorly...but this is just an opinion, what I would do is take a clone off of a low branch that doesn't have a fully formed bud, basically one that didn't get much light and root it. I have taken clones off of flowering plants indoors the same way and never had a problem, but they were around 4 weeks in bud. One thing to remember is that when you do re veg it after it having bud on it it will grow a little funny, don't be alarmed it will end up just fine
